If this is remotely true, then schools have either always had these functions, or there was a great tipping point where the schools were dramatically repurposed worldwide. Taking children out of the farm workforce was actually a huge negative; so much so that laws were passed to require their attendance - everywhere, essentially. Vaccines and suppplemental nutrition are only a very modern idea. Children brought their own lunches, and suffered from now mostly-extinct diseases. Schools, even general education, existed before the poor had a real path to higher education. Doctors and lawyers were admitted based on criteria like if their fathers had attended - thus excluding the poor a priori. You're 0/3. So when are you claiming this great sea-change in schooling occurred? Coincident with the fluoride-based 5G mind control?
